from washington, d.c. tonight's lead, the end of an era. for more than 20 years republicans have calmed to the one policy that's crippled our ability to get things done in washington. do you remember this? >> read my lips. no new taxes. >> read my lips, no new taxes. george h.w. bush hammered that mantra to win the white house in 1988. but just two years later, the reagan deficits were skyrocketing and president bush was forced to change his most famous line. >> long and bitter battle over the budget officially ended last night. president bush put his signature on the deficit reduction package, including $140 billion in tax increases. >> tax increases. that was a turning point for the modern republican party. the right wing went crazy. and george bush lost re-election. since then the party's been committed to never compromising on the tax issue, no matter the deficit. no congressional republican has voted for an increase in taxes since 1990. think about it. for nearly a quarter of a century, no new income taxes. in the current congress, 236 house republicans vowed never to raise taxes.
